First, make sure that you’re on the latest version of the Chrome browser on your phone (check iTunes here and the Play store here). Now, under the Settings menu of Chrome, you’ll find a Bandwidth management section. In there, you’ll want to tap the Reduce data usage label and, on the next screen, touch the OFF button to ON.

You should now see a chart which displays the amount of data Chrome is saving you. Neat, right?

Of course, this isn’t Google’s first attempt to keep you from bursting through the ceiling of your mobile data plan. Android 4.0+ actually has a built-in Data usage menu where you see how much you’ve used in a month’s time or even cap yourself if you so desire.

To check this out, simply go to your Android Settings app (find it either in your app drawer or in the notifications pulldown window) and click Datausage. There, you’ll find a chart showing your data usage, and also options to warn you or even cap you at a certain level of data (defaulted for 2.0 GB).

You can also turn mobile data completely off from this menu — which would, of course, impede your ability to read Yahoo Tech from your smartphone. Tough call. Better stick with the Chrome update for now.
